Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections - java

I'm getting the below error while giving docker-compose up.
springbootapp | org.postgresql.util.PSQLException: Connection to localhost:5432 refused. Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections.

The error is definitely due to postgres is not running correctly or the app is not able to communicate to postgres. Use below docker-compose file and check.
version: '2'
services:
postgresql:
image: postgres:10.4
volumes:
- ./postgresql/:/var/lib/postgresql/data/
environment:
- POSTGRES_USER=someuser
- POSTGRES_PASSWORD=
ports:
- 5432:5432
You can always use following command to check if db is accepting connection.
psql -h [HostIP] -U [db_user] -d [db_name]


I had same problem. the solution is simple.
first open docker app,
in Terminal process;
then you have to go to the directory where the docker-compose.yml
file is located.
then write docker-compose up
next, open pgAdmin app and choose db to your spring project,
next, enter the password and username found in docker-compose.yml
(username: image, password: POSTGRES_PASSWORD),
finally run the spring boot project.

Feign retryable exception error in Docker

I have created 4 services Eureka service, Gateway service, Authentication service and User service. Authentication and User service are routing through gateway service on port 8000 and FeignClient is used to communicate between Auth and User service for creating user and authentication.
My services are running fine on local server but when docker images are created I'm getting a Feign retryable exception error.

The documentation can be found in https://www.jbpm.org/learn/gettingStartedUsingDocker.html. And some examples in https://github.com/jboss-dockerfiles/business-central/tree/main/docker-compose-examples.
Can you help me? I have been trying several suggestions but none works.

If you don't use it in standalone.xml, You can disable this by remove :

docker compose with services and mongo databases throws error opening socket

I've two services, these are application.yml's:
category-service -> application.yml
spring:
application:
name: category-service
data:
mongodb:
host: categoriesdb
port: 27017
database: categoriesdb
server:

productcatalog-service -> application.yml
spring:
application:
name: productcatalog-service
data:
mongodb:
host: productsdb
port: 27018
database: productsdb
server:
port: 8080
And docker-compose:

services:
productcatalog-service:

build:

ports:

categoriesdb:

To sum up, I'd like to run these two services using one docker-compose, each service could have one mongodb assigned to it. If my thoughts about architecture are wrong, please correct me.
Thank you for help!

it seems productsdb needs change:
productsdb:
container_name: productsdb
image: mongo:latest
volumes:
- ./data/products-db:/data/db
ports:
- 27018:27018

if you use spring boot 2.4.0 try to downgrade version to 2.3.5

its not localhost when you are using docker container for each service.
change: hosts: localhost
to: hosts: couchbase.lcl

Why I have a connection refused error when starting rabbit by docker-compose?

I run sprinboot app, front (in react), database and rabbitmq in docker-compose. When I run it everything works except rabbitmq. I had an error - "Connection refused".
docker-compose:

Spring boot properties:
spring.rabbitmq.address=localhost
spring.rabbitmq.port=5672
spring.rabbitmq.username=guest
spring.rabbitmq.password=guest
I'm using ldap also, and I want to add users to rabbitmq on start. I can do it by adding commands to docker-compose?
Spring boot ldap config:
#Configuration
#EnableLdapRepositories
public class LdapConfig {
#Bean
public LdapContextSource contextSource() {
LdapContextSource contextSource = new LdapContextSource();
contextSource.setUrl("ldap://localhost:18889");
contextSource.setBase("dc=example,dc=com");
return contextSource;
}
#Bean
public LdapTemplate ldapTemplate() {
return new LdapTemplate(contextSource());
}
}

I figured it out, in the docker compose part responsible for the spring application, I had to specify the network mode:
server:
build: ./mlogger
ports:
- "8000:8080"
depends_on:
- database
- rabbitmq
network_mode: "host"

Inside a container, localhost is the container itself, not the host it is running on. Components are visible to each other with their service names. Insead of connecting to localhost:5672, connect to rabbitmq:5672, and it should work. Do the same for the database as well.
